For preventing the high-level radioactive waste from entering the biosphere, it is desirable that the waste is petrologically immobilized in a highly inert and insoluble form. The present research program aims to solidify the radwaste as ceramics. Of compounds, titanates are expected as the most suitable materials which are capable of keeping the radwaste for the required long period. In this paper, a review of ceramic waste forms, especially Supercalcine and SYNROC, is given, and the objective of the present research is shown. The following studies are included : (a) chemical reactivity of starting materials in the formation of radwaste-containing compounds, (b) crystal chemistry of compouds, (c) thermodynamic properties, (d) compatibility between the compouds and geological formations.
